Abstract
A femoral prosthesis and a knee prosthesis are provided. The femoral prosthesis includes a condyle surface having a first surface section contacting a tibial joint surface over a first range of flexion angles and a second surface section contacting the tibial joint surface over a second range of flexion angles; the first range of flexion angles from a first to a second flexion angle; the second range of flexion angles from the second to a third flexion angle; the first flexion angle selected from −20° to 0°, the second flexion angle selected from 45° to 75°, the third flexion angle selected from 50° to 90° and the third flexion angle greater than the second flexion angle; the first surface section having a radius of curvature of a constant length, and the second surface section having a radius of curvature that decreases from a front end to the rear end.
